I assume that you mean 16550 UARTs.  Most cards that come as a COM1: only 
but are expandable to 2 ports are usually socketed for the second UART; 
it's a simple matter to replace that 8250 (or 16450) with a 16550.  The 
problem there is that you are limited to COM2: for the '550; I've tried 
to pull out the 8250 and put in a socket for COM1: on a couple of times; 
normally, I end up toasting the card. B-(

However, Jameco has a 16550 card (part # 67053, product JE1062A) for 
$39.95; rather steep for a serial card (given the cheap ones are about 
$10...); but it has one 16550 and can take another.  (2nd port: part 
32301, product SSP5; $24.95.  Includes UART, cable, and line 
driver/receiver chips.)

Howzat?
